Answer:
The correct option is 2. The range of the function is {-6,-18}.
Step-by-step explanation:
The given function is
[tex]f(x)=3x-12[/tex]
Domain is the set of all possible inputs and range is the set of all possible outputs.
It is given that the domain of the function is {-2,2}.
For x=-2.
[tex]f(-2)=3(-2)-12=-6-12=-18[/tex]
For x=2.
[tex]f(2)=3(2)-12=6-12=-6[/tex]
Therefore the range of the function is {-6,-18} and option 2 is correct.
